Kids often come down with sore, scratchy throats. Colds and other viruses are usually to blame. Irritants such as smoke in the air can also make you feel raw.
Strep throat is different -- it’s caused by bacteria. You need to know whether you or your child has strep or another illness so you can get the right treatment.
How Do I Catch It?
Strep throat is an infection of the throat and tonsils. Bacteria called group Astreptococcus cause it. They live in the nose and throat. You can get the infection from someone who is sick with strep A bacteria or is a carrier of it.
You can infect yourself if you touch something a person with strep has coughed or sneezed upon and then brush your eyes, mouth, or nose with your hand. You can also get sick if you share a glass or other personal item with someone who has strep.
Strep is most common in children and teens. Adults can sometimes get it, too.
With strep, the sore throat comes on quickly. Your throat feels raw, and it hurts to swallow.
Strep is also more likely to cause these other symptoms as well:
- A fever of 101 F or higher
- Red, swollen tonsils
- White patches in the throat
- Tiny red spots on the roof of the mouth
- Appetite loss
- Nausea, vomiting
Call your doctor if you or a child in your care has these symptoms.
How Is It Diagnosed?
Your doctor will ask about your child's symptoms. The only sure way to tell strep from viruses that cause a sore throat is with a test. There are two kinds:
Rapid strep test: It can identify a case in just a few minutes. The doctor will gently hold down your child's tongue with a depressor. Then, she will use a cotton swab to take a little bit of mucus from the back of the throat.
You'll get the results in 20 minutes or less. If the test is positive, which means strep is there, the doctor will prescribe antibiotics to treat it.
If the test is negative, which means the strep bacteria could not be found, the doctor might send the sample to a lab for a follow-up that takes longer.
Throat culture: She will rub the sample from the throat swab onto a special dish. If your child has strep throat, streptococci bacteria will grow in it.
It usually takes about 2 days to get results from a throat culture. It can confirm whether your child has strep throat or not.
Your doctor will prescribe antibiotics to kill the bacteria that cause the infection. Most treatments last for about 10 days. The medicine can make your child's symptoms go away faster and help prevent complications.
Make sure your child takes all of the doses. Stopping the medicine too early can leave some bacteria alive. These can make your child sick again. Be sure to tell the doctor if your young one is allergic to any types of antibiotics.
If the strep test is negative, a virus likely caused the sore throat. Your child doesn't need antibiotics because these medications don't work on viruses.
Try these home treatments to ease symptoms:
- Gargle with a mixture of a quarter-teaspoon of salt and 8 ounces of warm water.
- Take ibuprofen (Motrin, Advil) or acetaminophen (Tylenol) to bring down a fever and ease pain. Don't give aspirin to children or teens. It can cause a rare but dangerous condition called Reye’s syndrome.
- Suck on a throat lozenge or piece of hard candy. Don't give small pieces of candy to children younger than 4.
- Drink warm liquids such as tea and broth. Or, suck on something cold such as an ice pop.
- Pass on orange juice and other drinks that have a lot of acid. They'll sting.
- Get lots of rest.
How to Keep It From Spreading
Have your child stay home from school or daycare until the fever is gone and he has been on an antibiotic for at least 24 hours. Same for you and the workplace. Other tips:
Strep complications are rare today, thanks to better diagnosis and treatment. Yet untreated strep can cause serious diseases, such as:
- Sinus or tonsil infections
- Rheumatic fever, which can damage the heart, brain, and joints
- A kidney disease called glomerulonephritis
Quick treatment with antibiotics can help prevent these problems.
